Winter Storm watch
Issued at Saturday, 8 December, 2012 3:48 PM
These regions could see significant snowfall amounts as well as a prolonged period of freezing rain.
A low pressure system near Montréal will move to lie near Sept-Îles Sunday morning. It will leave significant snowfall amounts Saturday night and Sunday, especially over the north shore. Additionally, strong to high winds will develop behind this low pressure system throughout these regions. Weather conditions will improve Sunday evening for a short while before another system arrives on Monday. A low pressure system from Colorado will reach the province of Quebec on Monday and bring with it a mixed bag of precipitation. Snow will begin late Sunday evening over the southern part of the province and during the day on Monday further east. It will give total accumulations of 10 to 20 centimetres. Road conditions will be hazardous Monday morning throughout Southwestern Quebec. This low pressure system is also accompanied by a warm front that will sweep across Southwestern Quebec early Monday morning, but should remain south of the St. Lawrence River. In the wake of the front, temperatures will climb above the freezing mark and turn the snow to rain. During this transition, some freezing rain could occur, especially in Montérégie and the Eastern Townships. The St. Lawrence and Ottawa valleys could see a prolonged period of freezing rain.
